When allocating RenderTextures via its constructor and calling Create afterward, they appear in the Untracked Memory in Memory Profiler, instead of contributing to Graphics & Graphics Driver as would be expected

Reproduction steps:
1. Open the attached "RenderTextures_1415558" project
2. Enter the Play mode
3. Capture a snapshot in Memory Profiler
4. Focus on the Game view and press Space
5. Capture another snapshot in Memory Profiler
6. Open the Compare Snapshots tab
7. Select the taken snapshots and compare their Memory Usage Overview

Expected result: In the second snapshot Graphics & Graphics Driver has increased more than Untracked Memory
Actual result: In the second snapshot Untracked Memory has increased more than Graphics & Graphics Driver
